WATER-CLOSET CONNECTION.

j Application led September 2, 1920. Serial No. 407,657.

To @ZZ fro/tom t 'may concern:

Be it known that l, Josnrrr J. Cosonovn, a citizen of' the United `States, residing` at Rutherford, in the county of Bergen and State of New Jersey, have invented certain new and useful lrnprovenients lin Tater- Closet Connections7 of which the followingis a specification, reference being had therein to the accompanying drawing.

This invention has relation to water closet connections of that class in which a thin metal ferrule is connected to the soil pipe and provided at its upper edge with a seat to receive a collar surrounding the closet outlet.

In water vcloset connections otl this character it has been customary to solder the lower edge of the terrule directly to the soil pipe or to a metallic adjusting nipple which is screwed into the soil pipe, but it s has been found that in certain parts of the Cil country, due probably to certain chemicals in the water a chemical or electrolytic action takes place that in time affects and eventually completely destroys the solder joint.

The object of my present invention is to provide, in water closet connections of' this character, a joining or connecting means between the iieiiule and the adjusting nipple that `will not be deleteriously affected by chemical or electrolytic action and iii carrying iny invention into effect l provide the adjusting` nipple of the connection with an inwardly and downwardly turned ledge or flange and bring the thin metal ot the ferrule down inside the downwardly projecting edge of' this flange and spin it under and around tho flange, so as to produce a firn'i inetal to metal and water tight joining ot these parts.'

As an added provision against any possible leak of water past the joint between the nipple and the ferrule, the edge of the downwardly projecting portion of the flange of the nipple may be formed with a groove and this groove filled with solder before spinning the end of the ierrule around the flange and the solder fused to the nipple and the ferrule after the spinning has been completed, thus producing a blind solder joint of the contacting parts of the nipple -and ferrule.

In the accompanying drawing in which I have illustrated my invention andiri which;

Fig. l, is a verticaly sectional view of niy j bulges outwardly and then extends inwardly at an angle so as to form a somewhat funnel shaped structure, and then extends Adownwardly so as to enter and fit within the adjustingnipple 6, that screws into the upper 'iok end of a soil pipe 7, that is formed with a laterally extending flange 8, which is connected to the closet base 9, by bolts 10.

The nipple 6, is formed with an inwardly extending flange 11, the inner and lower edge of this flange extending downwardly to form a rounded shoulder 12, that is closely embraced by the lower edge portion of the ferrule 5, which is spun around the rounded shoulder 12, after the 'ferrule has been inserted in the nipple, the portion of theV ferrule which extends inwardly at an angle resting upon the inner upper edge of the 'flange 11, and this constructionl and arrangement of parts serving to hold kthe nipple and the iferrule in strongandwater tight connection under all conditions of service.

while the Seal afforded by spinningthe,

edge of the ferrule around the flange of the nipple in the manner abovedescribed and as illustrated in Fig. 1, of the drawing will be found to besufliciently tight for all practical purposes, I have made provision for an absolute hermetic sealrbetween the ferrule and nipple, as shown in the modification Fig. 2, and wherein, in addition to having the lower edge of the ferrule spun around the flange 11 as in Fig. 1, a groove 13, is formed in the rounded shoulder 12, and this groove is filled with solder before `the edge of the ferrule is spun around the same and the solder, designated 14, is fused to the nipple and the ferrule, thus `:forming a blind solder joint that will constitute a, perfect hermetic seal and in whichV` the solder is so covered by Vtheedgefo the ferrule as top fbe protected against chemical orV electrolytic action to any appreciable extent. Iclaim: 1. A water closet connection comprising a. metallic ferrfule adapted to receive the outlet projection of t closet bowl, u nipple adapted to be connected to a drain pipe, rMid having an inwardly projecting flange with a downwardly projecting shoulder, the said errule extending into seid nipple and the lower end of the ferrule being spun around said shoulder. l n f 2. A Water closet connection comprising JOSEPH J. oosenoVE.
